While sunlight can cause wrinkles, the red glow from LEDs may help smooth them out, finds a new study.

A light-emitting-diode (LED) is a semiconductor diode that emits light when an electric current is applied in the forward direction of the device, as in the simple LED circuit.

The red LEDs do this by altering the interactions between water and elastic proteins in the skin.

In a new study, Andrei Sommer and Dan Zhu of the University of Ulm in Germany, found how water molecules in the skin interact with different substances.

They found that water molecules close to a hydrophobic, or “water-hating”, substance formed a slippery crystalline layer, and those surrounding a hydrophilic, or water-loving, substance were glue-like.

It is known that Elastin, the fibrous protein that gives skin its elasticity and prevents wrinkling, is hydrophobic.

However, with age, fatty acids, amino acids and calcium salts build up on the elastin fibres, and make them hydrophilic.

It makes the water film around the fibres increasingly glue-like, which makes them to stick to the surrounding tissue and reduce their elasticity.

It has earlier been confirmed that red light with a wavelength of around 670 nanometres can render more mobility to the water molecules close to hydrophilic substances.

Thus, the researchers aimed powerful red LEDs at the skin around the eyes for 90 seconds daily for 10 months.

They observed a significant reduction in wrinkles after applying red LEDs.

“The result was rejuvenated skin,” New Scientist quoted Sommer, as saying.

Such LEDs have also been used earlier for reversing eye damage and promote wound healing.

A University College London research team has reported the first known case of someone born without the ability to recognise voices, a rare condition which is scientifically known as phonagnosia.

The researchers are urging other people to come forward if they think they have also grown up with the condition.

Reporting the case in the online edition of the journal Neuropsychologia, the researchers revealed that a woman could not recognise people by their voice, including her own daughter whom she has great difficulty identifying over the phone.

known as KH, the 60-year old successful professional woman avoids answering the phone where possible, and for many years has only answered ‘booked calls’. She books calls with friends or co-workers, so that she knows who to expect when the telephone rings at a certain time.

KH was aware from an early age that there was something she couldn’t do that others clearly could, but it was only when reading an article in a popular science magazine years later that she finally understood her lifelong problem.

Though the article discussed prosopagnosia in which people have severe difficulty recognising faces, KH realized she might have the vocal analogue of prosopagnosia, and contacted the magazine.

The magazine then put her in touch with UCL’s Dr Brad Duchaine, the co-author of the paper.

“Occasionally, people have experienced problems recognising voices following a stroke or brain damage, but this is the first documented case of someone growing up with this condition. We suspect that there are other people out there with similar problems, and we’d like to get in touch with them. If you think you might be phonagnosic, please contact us,” Dr. Duchaine said.

“Voice recognition may not seem as important as face recognition, given that failing to recognise someone in front of you can cause much more social anxiety than not recognising them over the phone. Yet we rely on voice recognition in our day-to-day lives, to identify people on the phone or those speaking on the radio,” Dr. Duchaine added.

During the study, Dr Duchaine and Lucia Garrido of the UCL Institute of Cognitive Neuroscience presented KH with a series of tasks involving the recognition of faces, voices, vocal emotions, speech perception and music.

They observed that KH struggled to recognise the voices of famous actors and politicians, and also had difficulty learning and recognising new voices.

Compared to a control group of volunteers, nearly all of whom identified the voices of Margaret Thatcher, David Beckham, Dawn French, Chris Tarrant, Joanna Lumley, Sean Connery and Ann Widdecombe, KH was only able to identify the voice of Sean Connery.

However, KH performed well on nearly all other tasks.

Phonagnosia has only been documented so far in people with brain lesions in the right hemisphere following a stroke or brain damage, and the mechanisms behind it are not well understood.

In KH’s case, a MRI brain scan showed no evidence of brain damage in regions associated with voice or auditory perception, and her hearing abilities were found to be normal.

A team of cosmologists from the University of the Basque Country has determined that the accelerated expansion of the Universe can be explained by dark ‘phantom’ energy.

To explain the majority of the phenomena occurring in the Universe, complicated calculations with a computer are required and which have to be based on appropriate mathematical models.

This is what the Gravitation and Cosmology research team at the University of the Basque Country (UPV/EHU) is involved in: analyzing models capable of explaining the evolution of the Universe.

One of the phenomena that standard models of physics have not yet been able to explain is that of the accelerated expansion of the Universe.

Although Einstein proposed a static model to describe the cosmos, today it is well known, thanks to supernovas amongst other things, that it is, in fact, expanding.

By measuring the quantity of light that gets to us from a supernova, we can calculate its distance from us, and its colour indicates the speed at which it is distancing itself from us.

The more reddish it is, the faster it is travelling. In other words, comparing two supernovas, the one that is distancing itself more slowly from us is a more bluish colour.

According to observations by astrophysiscists, besides supernovas distancing themselves from us, they are doing so more and more rapidly, i.e. distancing themselves at an accelerated velocity, just like the rest of the material of the Universe.

The energy known to exist in the Universe, however, is not sufficient to cause such acceleration.

Thus, the theory most widely accepted within the scientific community is that there exists a ‘dark energy’, i.e. an energy that we cannot detect except by the gravitational force that it produces.

In fact, it is believed that 73 percent of the energy of the Universe is dark.

The unique characteristic of dark energy known to us is that it possesses repulsive gravitational force. That is, unlike the gravity we know on Earth, this force tends to distance stars, galaxies and the rest of the structures of the Universe from each other.

This would explain why the expansion of the Universe is not constant, but accelerated.

Such powerful dark energy is known as phantom energy, with which the Universe is able to expand to such an extent that the structures we know today would disappear.

This research group considers that the phantom energy model may be the most suitable to explain the accelerated expansion of the Universe.

This decision has worked to provide an effective computer that is well suited to the demands of a large network. The problem is that a number of employees are probably not used to using Macs and they will probably need a bit of training to get them in line.

This isn’t a problem since there are many options for Mac OS X leopard training. This latest operating system from Mac offers a lot of cool features and a sleek decision, but it is worthless if the employee doesn’t know how to make the most of it. Just spending a little money on a refresher course should have all your workers doing much better on the new system and greatly improving your overall efficiency. This could take place in the form of a seminar or a course. There are also online options that they can take in the background of normal business. This may be a better way to get the training done if your employees already know some of the basics.

If you want to make the jump to Macintosh, then you should remember to include Mac leopard training in the package.

In an unexpected turn of events, Pakistan Cricket Board today fired national coach Geoff Lawson who claimed he was taken by surprise by the decision. PCB Chairman Ejaz Butt took the decision and the Australian was given three months pay as compensation as per his contractual clause.

“The decision to release Lawson has been taken by the Chairman,” a Board official said. “Lawson’s contract was to expire next year but the PCB wants to make a fresh target and build a new set-up.

So it was decided to release him with full compensation,” said another official. However, Lawson who had a meeting with PCB Chairman today, said he was not aware of the development.

“I have not been informed so far about my dismissal,” Lawson, who took 180 wickets in 46 Tests and 88 in 79 one-day internationals between 1980-89, said. One PCB source said Lawson was upset in the meeting as Butt did not bother to ask him anything about the problems he faced as coach or the team issues.

After the meeting, Lawson returned to the national academy and was preparing to have a net session with Salman Butt and Kamran Akmal when media people approached him for his comments. “Indications are that things didn’t go well in the meeting,” one source said.

Lawson’s removal led to rumours that former captain Javed Miandad will take over but when contacted he firmly denied he was interested in the coaching position.

UPDATE – A new Joystiq interview with ESA president and CEO Mike Gallagher sheds serious doubt on the reports of public exhibition days that we previously heard.

Asked directly about public days, he said, “I wouldn’t expect that.” Pressed if the idea had been discussed, he mentioned that a survey was sent out, and it was “part of the discussion, but didn’t receive stand alone attention.” Sorry eager gamers, it looks like this particular expo is still press only.

ORIGINAL STORY – The Electronic Software Association has given official word on its plans for next year’s E3 video game media event, confirming some details, and remaining oddly silent on others. As previously reported, the event will take place June 2-4 at the Los Angeles Convention Center, which was confirmed by today’s press release. The company plans to make this a much larger event than the scaled down E3 we’ve seen the past few years, but right now the organization is being quiet about exactly what that means.

While the press release does talk about a larger show — particularly referencing “increased booth sizes” and “increased qualified audiences,” it strangely doesn’t mention what was for many the highlight of the recent news: public attendance. This could mean that the event opening its doors to the public was just a rumor. However, the dates given for the event, June 2-4, are the ones that were earlier reported to be for media and industry professionals only. This means that the ESA might be treating the supposed public days (June 5-6) as a separate event and plan to make that announcement official at a later time. We’ll keep you updated as we hear more.

Thousands of tiny gold pins which lay hidden in a desk drawer for 40 years have been described as one of Britain’s most important archeological finds.

According to a report in the Telegraph, the artifacts were part of a dagger buried with a warrior chief, near Stonehenge, nearly 4,000 years ago.

The pinhead-sized studs form an intricate pattern on the handle of the dagger, but archeologists failed to realise their significance when they excavated the burial mound in Wiltshire - known as Bush Barrow- in 1808.

Now, they are to be re-united with other priceless artifacts unearthed at the site and put on show at the Wiltshire Heritage Museum in Devizes after Niall Sharples, a senior lecturer at Cardiff University turned out his predecessors’ desk and discovered them in a film canister labelled Bush Barrow.

In the 1960s, the gold was taken away for examination by Professor Richard Atkinson, a Cardiff University archaeologist well known for his work at Stonehenge and nearby Silbury Hill.

“We think he recognized what they were but then he died and they were rescued by his successor Professor John Evans who put them in a drawer in his desk,” said Wiltshire Heritage Museum director David Dawson.

“Professor Evans died in 2005 and the gold studs have now been found by Niall Sharples, who is going to return them to us,” he added.

The gold pins, thought to come from Ireland, were fashioned by craftsmen in Brittany, France, and inlaid in an intricate herringbone pattern into the handle of the ceremonial dagger, which had an eight inch bronze blade.

It is the richest and most important Bronze Age grave on the Salisbury Plain and in Britain, according to experts.

According to David Dawson, the director of Wiltshire Heritage Museum, “It’s an unbelievable find”.

“The gold studs are remarkable evidence of the skill and craftsmanship of Bronze Age goldsmiths - quite rightly described as ‘the work of the gods’,” he added.

Young people with Attention-Deficit Hyperactivity Disorder (ADHD) are not only at greater risk of smoking, but tend to become more seriously addicted to tobacco, according to a new study.

Researchers found that individuals with more ADHD-related symptoms, even those who don’t have the full syndrome, are at greater risk of becoming dependent on nicotine than those with fewer symptoms.

ADHD is a developmental disorder affecting about three to five percent of the global population. It is typically present during childhood, characterised by a pattern of impulsiveness and inattention, with or without hyperactivity.

“Knowing that ADHD increases the risk of more serious nicotine addiction stresses the importance of prevention efforts aimed at adolescents and their families,” said Timothy Wilens, director of the Substance Abuse Program at the Massachusetts General Hospital (MGH), who led the study.

Several studies have shown young people with ADHD are more like to smoke and to start smoking at an earlier age. The current investigation was designed to examine whether ADHD also increases the severity of nicotine dependence.

Participants were taken from two long-term studies - one in boys and the other in girls - that analysed a variety of factors in children and adolescents with ADHD compared with a matched control group.

Participants completed a standardised questionnaire evaluating smoking history and levels of tobacco dependence in current smokers. Responses from 80 participants with ADHD and 86 controls, all ranging from age 15 to 25, were available for analysis.

While 69 percent of participants with ADHD had ever smoked and 41 percent were current smokers, only 44 percent of controls had ever smoked, with 17 percent currently smoking, according to an MGH statement. The report appeared in the Journal of Paediatrics.

Smokers with ADHD began using tobacco about a year and a half sooner than did control group members, and moderate or higher levels of nicotine dependence were reported by 21 percent of AHDH participants but less than one percent of controls.

The study’s findings also suggest biological mechanisms that may underlie both ADHD and nicotine dependence.
